Daria Kasatkina held her nerve to reach her first ever Grand Slam semi-final as she saw off Veronika Kudermetova 6-4, 7-6(5) in a tense Court Philippe-Chatrier contest at Roland-Garros on Wednesday.
The 25-year-old, a quarter-finalist in Paris in 2018, served for the match at 5-4 in the second set only to get nervous and let slip a 6-1 lead in the tiebreak before finally clinching victory.
Kasatkina, the No.20 seed, will meet either world No.1 and former champion Iga Swiatek or American Jessica Pegula in the semi-finals on Thursday.
